SIP Trunking Providers

The old fashion telephone system where bundles of real wires could be seen protruding from one place to another to connect to a telephone device inorder to make overseas calls no longer exist while making calls through SIP trunking providers.

SIP means ‘Session Initiation Protocol’. In a SIP technology, once a call is made, the speech is first compressed to data packets and passed through the internet. While passing the data packets are decoded back to speech and the receiver is able to hear clear voice. This is how SIP technology functions. Some of the leading SIP trunking providers are mentioned here below:
